Dear Ms. Buchl-Morales: We are pleased to submit the following proposal for Amendment No. One, Units D and E Diaphragm Revisions and Unit J Wall Revisions, IBC Review and Drafting. This letter serves as a supplement to our referenced agreement. The terms and conditions established by the agreement are unchanged except as noted below. A. PROJECT UNDERSTANDING We understand that the City of Renton has requested revisions to the Accessory Dwelling Units (ADU) Models D and E and Model J. Initial layouts for Models D and E have diaphragm openings that appear to exceed the permissible diaphragm limits established in the International Residential Code (IRC). The current designs are based on IRC compliance. For Model J, several shear wall segments are too short for IRC compliance. The City of Renton will have an in-house engineer provide analysis of these openings meeting International Building Code (IBC) requirements, as well as analysis of the Model J walls. The City has requested that proprietary Simpson Strong-Tie wall panels be used at the noted Model J wall locations. It is expected that several notes or one detail may need to be added at each location, at the request of the City engineer, with the affected sheets being sealed by the City engineer. This may affect 9 total units, including Models D1, D2, and D3; Models E1, E2, and E3; and Models J1, J2, and J3, with a further 9 mirrored layouts, for a total of 18 drawing sets affected. Reid Middleton has been asked to review the design and analysis work of the City engineer, provide review comments, and provide drafting services to update the drawings for the 18 models.
